I love '2 Hearts' and personally think it was a great comeback. If I had to choose another though, it would be 'The One'. I imagine it would have been much better received and been a bigger commercial success - it's the sort of glittery dance-pop music that fans would have gone mad for if this dropped as her comeback, particularly after the success of 'I Believe in You', and it's proved to be a fan favourite since, too. It's got a wintery tone to it as well; I think it could have really suited the November release.

Answer to first question...'The One' of course should have been the lead for this project, it would have been a massive hit instead of it being bumped to single #4 with only a digital release and a crappy music video. That was a total injustice to a song this magnificent and honestly could have given her 8th and final UK #1 single. I also think that 'White Diamond' got wrongly shafted and that should have at least made the album, or maybe make her big comeback single a double a-side 'The One/White Diamond', now that would have been awesome.

This is what I think this era should have went =

Single #1 = 'The One/White Diamond' (or maybe just 'TO', which could have worked just as well)Single #2 = 'Like A Drug'Single #3 = 'Wow'Single #4 = 'In My Arms'

For the American Market = 'Speakerphone', 'Like A Drug' & 'In My Arms'.

Answer to the 2nd question is No, I do not think that '2 Hearts' was a good lead single at all, because firstly it doesn't represent the album at all and secondly it doesn't have that wow factor like some of the other tracks do. I think maybe this should have been a promo release only.

That said, I love 2 Hearts and think its one of her best, it was a good idea to release something people didn't expect but I guess the public wanted something more "Kylie"

This is my sentiment exactly. I personally think '2 Hearts' showed that X was an era where she was going to take chances and experiment with sounds and styles more; very much a "I've still got more to give and will not be beaten" type of attitude. Plus it's a genuinely great song.
